INSECT-PATHOGENIC FUNGUS, SPORES, COMPOSITION AND USE OF SAME

摘要

Novel strains of the insect-pathogenic fungus, Metarhizium var. anisopliae fungal strain BNL 101 deposited in the CABI UK Centre, United Kingdom, having ICI CC Number 06833; or BNL 102 deposited in the CABI UK Centre, United Kingdom, having ICI CC Number 506834;or a culture having the identifying characteristics thereof,are disclosed. The present invention also discloses methods of using the fungal strains, and spores obtained therefrom, to control insects, and provides a natural pest control preparation. The preparations and compositions comprise several unique and desirable features,such as a wide host range or alternatively a selective host range, and a consistent pathogenicity. The preparations and compositions have a high virulence(insecticidal activity), that is 2 times to 3 times, or greater, mor virulent (insecticidal) than compositions or preparations that do not contain the preparation or composition, and especially that do not contain the BNL 101 or BNL 102 fungal strain, or spores therefrom. The fungal strains also provide for a high spore yield in production, and possess a high stability in the field.
